It depends on what crypto you use, they all have upsides and downsides. Bitcoin cash has incredibly long confirmation times like Bitcoin, you can only sell cheap stuff with no confirmation because it’s not safe (you can double spend if you’re a miner)

I exchanged Bitcoin cash with extremely low fees for moving it. But I don’t know if it actually has a future, most people are not really bullish on it. Cryptos have to be used as a form of exchange to have value on the market. I thought Nano with no fees had a future, but that’s a feature most people didn’t care about

But you don’t have to choose, offer bch, monero, Bitcoin lightning, etc. and let the user decide what crypto they want to pay with
